Grouting reinforcement composite material for riverbed sand soil layer as well as preparation method and application of grouting reinforcement composite material
The invention belongs to the technical field of horizontal directional drilling, and particularly relates to a grouting reinforcement composite material for a riverbed sand soil layer and a preparation method and application. According to the grouting reinforcement composite material for the riverbed sand soil layer, the curing mechanism of isocyanate and polyol and the curing mechanism of cement and water are matched with each other, curing of the sand soil layer is enhanced, stable drill holes are formed, horizontal directional drilling construction is facilitated, and the construction efficiency is improved. Meanwhile, by adding nano silicon oxide, polyvinyl alcohol, fly ash and ethyl acetate, the curing strength of the sand layer is further improved, and therefore the technical problems that in the prior art, the effect of grouting and reinforcing the riverbed sand layer through cement and other curing agents is poor, and stable drill holes are difficult to form in the riverbed sand layer are solved.
本申请属于水平定向钻技术领域，尤其涉及用于河床砂土层的注浆加固复合材料及制备方法和应用；本申请提供的用于河床砂土层的注浆加固复合材料通过利用异氰酸酯、多元醇固化的机理和水泥、水固化的机理相互配合，加强了对砂土层的固化，形成了稳定的钻孔，有利于水平定向钻施工，同时还通过纳米氧化硅、聚乙烯醇、粉煤灰以及醋酸乙酯的添加，进一步改善了砂土层的固化强度，从而解决现有技术中水泥等固化剂注浆加固河床砂土层效果不好，难以在河床砂土层中形成稳定钻孔的技术问题。
